A LNAPL skimming remedial system is currently being installed at BP Concorde Service Station (the site). The site is located in Virginia, Free State. The location of the system is on the western boundary of the service station on vacant land. Geostream Africa is the subcontractor on site. A TLB was used to excavate trenches and well chambers. Before the start of work a routine check on the TLB was conducted by the H&S officer and the TLB operator. During their check they noticed that the front tyre of the TLB had less pressure compared to the rest.
